چکیده
ABSTRACT Cherry tomato cultivation in the semi-arid region of northeastern Brazil is limited by water scarcity, so it common to use sources with high concentrations salts this region, which have a deleterious effect on plants, can be alleviated through management strategies, and fertilization nitrogen stands out. This study aimed evaluate growth, gas exchange production cherry under irrigation saline fertilization. The experiment was carried out screened environment at CCTA/UFCG Pombal - PB from October 2020 February 2021, using randomized block design, 5 × factorial scheme, five levels electrical conductivities ECw (0.3; 1.3; 2.3; 3.3 4.3 dS m−1) doses ND (50; 75; 100; 125 150% recommended dose for crop), three replicates. Irrigation salinity 0.3 m−1 reduced stomatal conductance, transpiration, CO2 assimilation rate components tomato. Nitrogen 50% recommendation transpiration conductivity associated intensified salt stress dry biomass accumulation

A split-split-plot design with three replications in two years of 2009 and 2010 was conducted to investigate the effect of different levels of irrigation water (main plot), salinity of irrigation water (sub-plot) and nitrogen fertilizer rate (sub-subplot) on maize growth rate and gas exchange. Irrigation treatments were I1 (1.0 crop evapotranspiration (ETc)+0.25ETc as leaching), I2 (0.75I1)...
